In this post we will be discussing how to set up application and infrastructure monitoring for Docker Swarm with the help of Prometheus. Swarmprom is a starter kit for Docker Swarm monitoring with Prometheus, Grafana, cAdvisor, Node Exporter, Alert Manager, and Unsee.

The Weaveworks team visited PromCon 2017 in Munich. One of our personal highlights was a deep dive into the past 12 months of Cortex, the basis of our monitoring and analytics capabilities in Weave Cloud.

Monitoring distributed applications is best approached using a combination of tools. Luke Marsden describes how Prometheus, openTracing and Weave Cloud visualization cover the bases to establish root cause of problems in distributed applications.

At KubeCon Europe 2017, Weaveworks Director of Software Engineering, UI/UX, David Kaltschmidt gave a presentation titled “Grafana is Not Enough: DIY User Interfaces for Prometheus.” In this talk, he discussed the Prometheus UI.What’s...

Weaveworks Director of Software Engineering Tom Wilkie was busy at CloudNativeCon + KubeCon Europe 2017. Between showing off Cubienetes and presenting browser metrics in Prometheus, he found time to discuss one of his personal projects....

After a particularly egregious outage was reported by a Weave Cloud user, we decided it would be a good idea to add some alerting to our front-end codebase. Alerting and metrics for Weave Cloud are handled using Prometheus, however, which...

During KubeCon, our Director of Software Engineering Tom Wilkie gave a presentation called “Behind the Iron Curtain: Getting Metrics From the Browser into Prometheus.”The ideaPreviously, Prometheus has been pigeon-holed as a monitoring...

Prometheus comes with its own query language called PromQL. It’s very powerful and easily allows you to filter with the multi-dimensional time-series labels that make Prometheus so great. But it can be daunting when you are faced with an...

The topic of how the services in Weave Cloud are instrumented came up in two discussions this week, so I thought I’d write a short blog post explaining all the moving parts. Instrumenting Requests For all services in Weave Cloud, we...

This is the story of how we manage our Prometheus config to avoid restarting Prometheus too often, losing all our history. It is a short, up to date write up of a talk I gave at the first London Prometheus meetup. In the beginning there...

We run a couple of replicated Consul services for Weave Cloud: one acts as a coordinator for the distributed WebSocket router backing Scope’s terminals feature, and the other for storing the state of Cortex’s consistent hash ring. This...

How would you answer the questions like “how much CPU is my service consuming?” using Prometheus and Kubernetes? In this quick post, I’ll show you how… First we need to think about where to get the information from. cAdvisor (from Google)...

If you use Prometheus, then you probably use Grafana. At Weave, we have Grafana dashboards for all of our microservices. When we want to understand our system, our Grafana dashboards are the first things we look at. To make the most out of...

KubeCon Seattle is Almost Here KubeCon Seattle is just around the corner and we hope to see you there Nov. 8-9. If you’re not familiar with KubeCon Seattle, the two-day event brings together thousands of Kubernetes technologists to hear...

tl;dr: Weave Mesh, an open-source gossip and CRDT communications library, gave the Prometheus Alertmanager exactly what it needed to be reliable and highly-available. As a former SoundCloud engineer, I’ve had the privilege of using...

In the last post in our series “Prometheus and Kubernetes”, Tom talked about how we use Prometheus to monitor the applications and services we deploy to Kubernetes. In this post, I want to talk about how we use Prometheus to monitor our...

In this post we discuss how to configure Prometheus to monitor your Kubernetes applications and services, and some best practices that we have developed around instrumenting your applications in a consistent fashion based on our experience...

In this post I discuss the various options and tradeoffs we encountered at Weaveworks when deploying Prometheus with Kubernetes to monitor Weave Cloud. This is the second post in our series on Prometheus and Kubernetes, the first being...
